+================
+
+NAME
+----
+perf-annotate - Read perf.data (created by perf record) and display annotated code
+
+SYNOPSIS
+--------
+[verse]
+'perf annotate' [-i <file> | --input=file] [symbol_name]
+
+DESCRIPTION
+-----------
+This command reads the input file and displays an annotated version of the
+code. If the object file has debug symbols then the source code will be
+displayed alongside assembly code.
+
+If there is no debug info in the object, then annotated assembly is displayed.
+
+OPTIONS
+-------
+-i::
+--input=::
+ Input file name. (default: perf.data unless stdin is a fifo)
+
+-d::
+--dsos=<dso[,dso...]>::
+ Only consider symbols in these dsos.
+-s::
+--symbol=<symbol>::
+ Symbol to annotate.
+
+-f::
+--force::
+ Don't complain, do it.
+
+-v::
+--verbose::
+ Be more verbose. (Show symbol address, etc)
+
+-D::
+--dump-raw-trace::
+ Dump raw trace in ASCII.
+
+-k::
+--vmlinux=<file>::
+ vmlinux pathname.
+
+-m::
+--modules::
+ Load module symbols. WARNING: use only with -k and LIVE kernel.
+
+-l::
+--print-line::
+ Print matching source lines (may be slow).
+
+-P::
+--full-paths::
+ Don't shorten the displayed pathnames.
+
+--stdio:: Use the stdio interface.
+
+--tui:: Use the TUI interface. Use of --tui requires a tty, if one is not
+ present, as when piping to other commands, the stdio interface is
+ used. This interfaces starts by centering on the line with more
+ samples, TAB/UNTAB cycles through the lines with more samples.
+
+--gtk:: Use the GTK interface.
+
+-C::
+--cpu:: Only report samples for the list of CPUs provided. Multiple CPUs can
+ be provided as a comma-separated list with no space: 0,1. Ranges of
+ CPUs are specified with -: 0-2. Default is to report samples on all
+ CPUs.
+
+--asm-raw::
+ Show raw instruction encoding of assembly instructions.
+
+--source::
+ Interleave source code with assembly code. Enabled by default,
+ disable with --no-source.
+
+--symfs=<directory>::
+ Look for files with symbols relative to this directory.
+
+-M::
+--disassembler-style=:: Set disassembler style for objdump.
+
+--objdump=<path>::
+ Path to objdump binary.
+
+--skip-missing::
+ Skip symbols that cannot be annotated.
+
+--group::
+ Show event group information together
